[erlang-questions] How to debug erlang

[Eckard Brauer]

Hello Oliver and Garret,

thank you for the helpful hints - indeed, I already found "Erlang in
anger", but didn't read it at the time - so I simply didn't remember.
The recon_trace I will definitely have a look on.

One more question: I believe to remember that I read at any occasion of
a possibility to create a backtrace from within a code snippet, but
didn't try it aut extensively at that moment, so I forgot about. Do you
have one more hint for that - or did I mix up things with any other
language?
